TPF Noob!
Well, I just picked up a used 135mm 2.8 Nikkor-Q non-ai lens. Lately I've been interested in the older Nikon lenses, and I came across this lenses at a great price. I knew it's have to be converted to ai since I'm using a D300. So being a mechanic I figured I'd attempt the lens conversion myself. I didn't think to take pics until I had the lens apart already. So if wanted I can take pics to show what was done if anyone needs.
It was surprisingly simple: Take the 5 screws out of the rear mount plate, make sure the lens is on it's closest focus point (1.5M), pull out the rear plate assembly. Next take out the single screw on the Aperture ring, and pull it off. Then notch out the ai-groove required, I took off the metering couple prong off to do it and just used a normal file. Then reassembled the lens, careful when reinstalling the aperture ring screw, as you'll have to find the recess where it goes to guide the aperture adjustment.
Here's s few pics of the conversion:
Here's a quick test shot I took with it on the D300 at 2.8:
